Augmented and virtual realities are introducing a digital layering to the human experience that will dramatically impact every city of the future. In “Multiplanar Humanity” we explore the complications and potential of a multi-layered world, starting with one of the more practical applications of augmented reality technology — construction, and a look at how the first city on Mars will be built. Then, we complicate the story, and take a peak inside that next, totally virtual layer of human civilization. From communication and leisure to education and love, this is the future of reality.
